Which of the following are true statements concerning the Neutral Axis? Select all that apply: The cross-section's Centroid always lies on the Neutral Axis The Neutral Axis is the line on the cross- section where there is no normal strain due to bending The neutral axis is always at the top of the member The neutral axis is perpendicular to the direction of beam loads causing bending. The neutral axis must be determined experimentally. We have not devised a way to locate it using equations.
